CONNECTIONS AND POWER
The UT FET47 requires 2 things in order to properly function: a 3 pin XLR
cable, and 48V phantom power.
The first is simple; plug the XLR cable to the output jack on the bottom of
the UT FET47. Then connect the cable to your recording device, preamp, or
mixing console. Ensure that the cable is properly working…
Sorry, we had to spell that out.
Engage 48V phantom power on your device. If your device does not provide 48V phantom power, an external, dedicated power supply will be required for operation.
HARDWARE CONTROLS
The UT FET47 is a cardioid pattern, large diaphragm, transformer-balanced condenser microphone designed for a very wide range of recording studio applications. It’s operation is fairly straightforward; and as with any microphone; the more attention given to setup and placement, the better the results will be. The UT FET47 features a high pass filter for eliminating subsonic information such as floor vibration and rumble, and a -10 pad for use in very loud sound pressure situations such as kick drum, amplifiers, and especially loud vocalists.
How to know if you need the pad engaged?
It is good practice, unless you are certain you will need it, to start without
the pad engaged. You will know you need the pad if the signal is distorted,
clipping, or ‘flatlined’ even after properly spacing the microphone from its
source. The pad will allow for an additional 10dB of headroom in the amplifier
circuit for these situations.
When to engage the high pass filter?
In studio recording, we feel it is usually good practice to record an audio
source at ‘full bandwidth’ and to precisely tailor any band-limiting in the
modern workstation. This provides much more accuracy than a single switch on a
microphone can provide; and the switch at this point is more a carryover from
an earlier time. There are a number of sound sources, however, where one can
be fairly sure that frequencies below the switch cutoff frequency are not
going to play a major part in the makeup of the audio source, or at least not
in the finished (edited/processed) form that the audio track will take. This
includes voice, guitar, drum overhead, and possibly some acoustic instruments.
This is particularly true of live voice broadcast (podcast, radio broadcast)
and narration (books on tape, etc). Because low frequencies have very large
waveforms, a high pass filter on the microphone can sometimes reduce the
chances of clipping or allow a slightly hotter signal to be captured, without
the damage from moving microphone stands, doors, and rumble from nearby
traffic, etc.
As a general rule, if engaging the HPF causes no audible loss to the ‘body’ of the source signal; it is safe to engage. If it does feel that it takes something away, and if the application is professional recording, then best to not engage the switch and tailor the signal at a later point in the process.
